During the first stage of a triaxial test, the cell pressure is increased from 2 MPa to 4 MPa. The first stage is undrained and the pore water pressure changes from 1 MPa to 2 MPa due to the increase in cell pressure. The value of the Skempton’s pore pressure parameters A and B if A_f = 0.4

Which of the following is the appropriate triaxial test to assess the immediate stability of an unloading problem, such as an excavation of a clay slope?

The results of CU test on compacted soil are given below:

Determine the cohesion intercept and the angle of shearing resistance in the terms of effective stresses.

A sample of dry sand is tested in the laboratory in a triaxial test under undrained condition. The sample failed at a deviator stress of 150 kPa under a cell pressure of 100 kPa. When the cell pressure becomes 200 kPa, the deviator stress at failure becomes

A saturated clay specimen of cylindrical shape having diameter 4 cm and length 9 cm is tested in an unconfined compression testing machine. The cohesion of the clay sample determined from the test is 2.5 kg/cm². Further it is noted that the specimen fails under the vertical load of “x” kg together with an accompanying additional deformation of 10 mm. The value of x is ______ kg.
